This article shows you how to troubleshoot yum. The content is concise and easy to understand. It will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

If you use HTTP as the YUM source, the specific settings are as follows:

1 install httpd installation package # yum-y install httpd

2 Mount ISO to create a local update source

# mount-t iso9660-o loop rh73.iso / mnt/cdrom

# cd / var/www/html/

# mkdir yum

# mount-- bind / mnt/cdrom yum

[root@localhost html] # vi / etc/yum.repos.d/yum.repo

[root@localhost html] # cat / etc/yum.repos.d/yum.repo

[RHEL]

Name=rhel6.3

Baseurl= http://192.168.1.130/yum/

Gpgcheck=0

Enabled=1

3 service httpd start # start the httpd daemon, otherwise you will be prompted that the relevant source cannot be found on other machines

Chkconfig httpd on # set up system services

4 test it

[root@localhost yum.repos.d] # yum clean all

[root@localhost yum.repos.d] # yum makecache

5 error report that unable to connect to YUM source

Loaded plugins: product-id, refresh-packagekit, security, subscription-manager

This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.

Http://192.168.161.1/rh73/repodata/repomd.xml: [Errno 14] PYCURL ERROR 7-"couldn't connect to host"

Trying other mirror.

Error: Cannot retrieve repository metadata (repomd.xml) for repository: rhel-source. Please verify its path and try again

First of all, confirm whether the HTTPD service is started.

Service httpd status

And check for firewall restrictions, or turn off the firewall

Service iptables stop

Second, if you still report an unable to connect error

Delete an authentication file

Rm-rf / root/.ssh/known_hosts

Once again, modify the / etc/yum.conf file if the verification error is also reported.

Change the gpgcheck=1 into gpgcheck=0

6 try again

[root@localhost yum.repos.d] # rpm-qa | grep telnet

[root@localhost yum.repos.d] # yum-y install telnet*

Installed:

Telnet.i686 1RO 0.17-47.el6 telnet-server.i686 1RU 0.17-47.el6

Dependency Installed:

Xinetd.i686 2vl 2.3.14-34.el6

Complete!

All right, YUM is fine.
